Abstract
An image forming apparatus includes a communication section that wirelessly communicates with an RFID tag on a toner supply container. Based on a state of communication between the RFID tag and the communication section, an amount of toner in the toner supply container is measured, or a rotational angle of the toner supply container is detected. Since it is unnecessary to additionally provide a member for measuring the amount of the toner or detecting the rotational angle, the number of components can be reduced.
